a little something i found that might interest you
"What you need:
1oz of good quality bud (quality does make a very big difference in this recipe!)
1cup Food Grade Glycerine (available from your local pharmacies or drugstores or health shops)
Cheesecloth
A glass bottle with a sealable lid
preferably metal.
A glass dropper bottle
Your computer exhaust or something to heat it consistently for days on end
NOT A HOT LIGHT
You can of course use considerably less amounts of pot for this recipe. You can use as little as 1 gram of finely ground weed in 8.5ml of glycerine. Increase amounts in proportion
so 1/4oz would get a 1/4cup etc etc.
Then you have to leave the weed in the glycerine for two full months (thats 6 weeks!), shaking it each and every single day at least once. My first batch I shook maybe 8 times daily, and had it consistently heated 10-20 degrees Celsius above room temperature.
This whole process can be exceedingly quickly accelerated by the extra heating and shaking. It can go from taking 6 weeks to 2, and if you have the right equipment, it can take as little as 14 hours. By simply putting mine in the exhaust of my laptop and keeping it there 24/7 except for when shaking, it was almost ready in about 2 weeks. If I had left it for another week it would have been perfect. The end product should be a pine green colour, and smell exceedingly strong.
Once you have let the drops sit for long enough for all the thc to have dissolved into the glycerine, than you can put it into a glass dropper bottle. If you want to check the glands of the Herb to see if there is actually any THC left, examine the Herb under a microscope before putting the bud into the glycerine, then simply take a piece out of the mix when you want to check it and examine it again under the microscope
the change will be very obvious, and you will be able to see if any trichomes remain on the glands. If either you see that there is no more thc left in the pot, or you can see the colour of the glycerine turn dark
or just wait the full 2 months (this is the best bet always).
You can use pure kief for this recipe as well, when you do this just use about 3x as much glycerine as you have kief, and put the glycerine in the bottom of a very tall and skinny bottle, then put the kief on top. Shake and heat the same as you would the normal drops. With kief you can actually see whether or not it is entirely dissolved, so simply bottle it minus the straining once everything has dissolved nicely
If you have an autoclave, or a pharmaceutical grade glass beaker with threadlock top, than this next method is for you!
Take 1oz of primo bud, not crushed but de-stemmed and totally and completely dried out. Toss them into a screw seal boiling beaker. Then, you must absolutely ABSOLUTELY use thread lock on the beaker. If you dont do this, its totally pointless to even try this method. Put the bud in the beaker with 1 cup glycerine, boil in your oven or on an autoclave at 155C or 311F. Leave for 36 hours. It should be boiling for most of this time, but air should not be escaping the beaker. Remove and let cool. Upon cooling it should have separated into a green oily substance (which you want to keep) and a black thick tar, which in this case tested at 12% THC. The green oily substance in this case tested at 88% THC. The bud should have completely and totally dissolved into the glycerine. That black tar stuff is all the plant material. It can be tossed if you like
or you could try drying it and smoking it, its up to you. (Thanks to Quanium for testing this for us!)
Once you have your drops, you can soak some of your normal bud in it to give it an extra little kick. Or you can put a few drops in a joint, or just on the top of a bowl in a bong. But by far the single best way to do this is to put just a few drops under your tongue and hold it there for about 2-3 minutes. Will make you go absolutely mad. The better herb you have, the better this concoction will be.
Dosage numbers:
Approximately 2-3 drops per dosage for a good time
equals about 6 bowls of good weed smoked in a bong, if the recipe is done properly.
This means that every ounce of herb and a cup of glycerine mixture you have, you will end up with approximately 4800 drops (or 1600 doses) if strained completely.
For only one gram of herb and 8.5ml of glycerine you will get about 60 doses at 3 drops each.
This is comparable to a normal approx 97 .3g bowls that you would get out of an ounce on an average basis.
Then of course there are those of you going "Well this sounds just too good to be true!" Well here is some chemistry for you non believers! Glycerine is a sugar alcohol, and thc is alcohol soluble. Simple chemistry then shows us then that the thc will be soluble into the glycerine given enough time. Now this said, it isnt a 100% alcohol or anything near it, which is why it takes so long for it to sit. But then why use glycerine instead of everclear or something like that and just make green dragon? Well unlike other types of alcohols, sugar alcohols are able to be absorbed exceedingly easily by the arteries underneath your tongue! And when the THC binds to the glycerine, this makes it easily absorbed into your bloodstream on a direct path for your brain! The absorption of THC into the bloodstream from smoking joints sits at about 15%, the amount for using a bong ranges from 25-35% approximately, and the amount for using a vaporizer or cooking ranges from about 45-55%. With the glycerine absorption method intake has been tested with various other drugs (mixed with glycerine as tinctures) with up to 90% absorption. This should be about enough proof I think to convice most of the doubters.
Now we all know that weed isn't unhealthy for you if taken in right, so what about glycerine?
Well, glycerine is in your toothpaste, in lubricants, skin care products, used in cough syrups
So its safe to ingest. Is it safe to smoke? Well glycerine is an almost globally used compound in everyone's favorite flavored smoke"
